The auto-rotate feature on the ThinkPad Twist running Windows 8 is controlled by the power manager module.    Early production models shipped with two different versions of this driver in the preload depending on date of manufacture (See details on versions GM6 and GM7 and initial functionality listed below).

 

UPDATED MODES OF OPERATION available NOV 30, 2012

 

Following the initial release of Twist, Lenovo updated the functionality to improve the customer experience in the 4 modes of operation - notebok/clamshell, stand, tablet, and tent mode.   These updates ensure the onscreen keyboard is more easily available, unwanted screen rotations / orientations eliminated, and the screen lock button functionality changes depending on mode.   These update require installation of GM8 version of the power manager and an updated BIOS version.   After these updates, the screen lock button will only lock the screen orientation while in tablet mode.   In other modes, this button will now flip the screen image - useful when shifting to tent mode.

 

To update, follow the instructions below to improve screen orientation in Microsoft Windows 8 on the ThinkPad Twist. For current users of the Twist, there is a new set of software updates that will enable better screen orientation and control operation. For new users to Twist, this same set of updates will insure consistent transitions to each of the four operating modes: Clamshell, Stand, Tablet, and Tent.  Full Tip with details available here on our support site.

 

Run ThinkVantage System Update to download driver updates. From the Start screen, type update. This will display the System Update App icon which will be located in the upper left corner of the display. Touch or click this icon to begin the update process. 

 

 Detailed update instructions are listed here

Background information on PRIOR functionality with GM6 and GM7 versions of power manager

 

 

 

1.66.00.12 is power manager (GM6) and only supports onscreen keyboard in tablet mode and may not fully support tent mode.  (1.66.00.14 ) is the downloadable version of GM6 

 

1.66.00.15  (1.66.00.17 on the web) is power manager (GM7) that provides the initial tent mode support and supports the onscreen keyboard in multiple modes.

 

Check the version of the Lenovo Power Management driver installed on your machine.

 

Note:  You need to be at driver version 1.66.00.15 or higher to use Tent Mode.

 

a. At the main Windows 8 start screen, press the Windows key and the letter X on your Keyboard.

b. From the popup list that appears, click on “Programs and Features at the top, with your mouse.

c. In the window that opens, scroll down the list and locate the "Lenovo Power Management" driver.  Scroll over to the right to verify the version number installed on your machine

d. If your driver is not at the correct level, download and install the driver from the link below.  If your driver is already at the correct level, please see the instructions below for the proper method to enable Tent Mode.

e. The installed version of the driver should show as 1.66.00.15 or higher.  

 

Note:  Once you have installed the driver, please read the instructions below for the proper method to enable Tent Mode.  Here are some of the different display modes and how to access them.

One way to easily get the screen back to the correct orientation (if it is inverted), is to use the CTRL + ALT + Arrow keys on the keyboard to rotate the screen to the desired position.  (Usually this is CTRL + ALT + Arrow Up)

Great fix!!! Every twist needs this driver.

 

Just one more request. I want to use tent model, when I connect to the external monitor. But after I connect to the external monitor, the rotation doesn't work on my laptop.
